The impact of COVID-19 on chronic pain in non-infected vulnerable South American subjects is unknown. Healthcare workers are at increased risk for CP. During the pandemic, many HCWs with CP kept working. Knowing how cognition is affected by CP in these subjects is an important subject for work safety. The attention domain has a pivotal role in cognition. Previously, the Continuous Visual Attention Test was applied to detect specific attention deficits in fibromyalgia patients. The present investigation described CP prevalence in (...) non-infected Brazilian HCWs during the pandemic and assessed HCWs’ attentional performance with the aid of the CVAT. This study was carried out at a reference University Hospital in Rio de Janeiro, Brazil. HCWs of both sexes, aged 20 or older, were interviewed from August to December 2020. A 90-second version of the CVAT was performed. The average reaction time to correct responses and the respective intraindividual reaction time variability for correct responses to target was determined. Omission and commission errors were also calculated. Then, for each participant we calculated the Z-scores of the CVAT variables based on the distribution of CVAT performance of 211 healthy subjects. HCWs with Z-scores > 1.64 were classified as significantly impaired. From the 154 selected HCWs, 72 reported CP during the pandemic. Post hoc ANCOVAs showed that the average correct VRT was significantly higher in the CP group than in the non-CP group. The percentage of participants with impaired VRT performance was 30% in the CP group and 16% in the non-CP group. The difference between these two propositions reached significance. As VRT is associated with the sustained-attention subdomain, our data suggest that this subdomain is disrupted in the CP group. (shrink)

Two Lagrangians L and L′ are equivalent if the equations of motion derived from them have the same set of solutions. In that case, a matrix Λ may be defined which has the property that the trace of any analytic function of Λ is a constant of the motion. We extend this trace theorem to the case of classical field theory and discuss some of the implications for quantum theory and for procedures for finding equivalent Lagrangians.

. The uniform prior distribution is often seen as a mathematical description of noninformativeness. This paper uses the well-known Three Prisoners Paradox to examine the impossibility of maintaining noninformativeness throughout hierarchization. The Paradox has been solved by Bayesian conditioning over the choice made by the Warder when asked to name a prisoner who will be shot. We generalize the paradox to situations of N prisoners, k executions and m announcements made by the Warder. We then extend the consequences of hierarchically (...) placing uniform and symmetrical priors for the probability p of the Warder naming Prisoner B, say. We prove that breaks of indifference and neutrality caused by assignment of uniform and symmetrical priors in lieu of degenerate indifference probabilities hold in general. Speaking of unknown probabilities or of probability of a probability must be forbidden as meaningless.

Preface -/- 1. 'Anima' and 'res cogitans'. The Cartesian idea of nature and mind as a residual concept. The first chapter discusses the genesis of the concept of mind in Cartesian Philosophy; the claim is advanced that 'res cogitans' is a residual concept, defined on the basis of a previous definition of matter as 'res extensa'. As a consequence, a contradictory ontology of the mind is Descartes's poisoned bequest to the following tradition of 'scientific' psychology. -/- 2. The Mathematical method (...) in the theory of the mind and the passions. The second chapter discusses the first ambitious attempt in this direction, namely Spinoza's theory of the mind and the passions in Ethics II and III; the topics treated are Spinoza's program of a mathematical science of the mind and his transformation of the genre 'treatise of the passions' into a would-be mathematical science of the motions of the soul. -/- 3. The definition of affections and the impossibility of reducing inadequate to adequate ideas. The third chapter discusses a tension in Spinoza project of a theory of the passions, namely a need to reduce concepts to pure mathematical definitions and the opposite need to keep inadequate imaginative definitions of the phenomena under scrutiny, namely the passions, in order to avoid a radical reduction of the subject-matter to the only truly existing reality (the world order in itself) that would leave the theory without any subject-matter at all. -/- 4. 'Conatus', 'potentia', 'vis'. Concepts of force in the theory of passions and the impossibility of eliminating occult qualities. The fourth chapter discusses the troubles arising in the original project deriving from difficulties in the treatment of dynamic concepts, such as the notion of conatus, which were an unavoidable consequence of Cartesian assumptions. -/- 5. Overview and discussion. Chapter five tries to draw a general discussion, focusing on the tension between the Cartesian assumptions and the actual practice in the new post-Galilean sciences, including attempts at giving birth to psychology or science of man. -/- Appendices I. The mind-body problem in Spinoza. II. Concepts of force in Newton and Spinoza. III. Materialist readings of Newton and Spinoza. IV. On the opposition of materialism and spiritualism and Geisteswissenschaften and natural science. V. Conatus, the idea of liberation and social theory in Spinoza. (shrink)

The aim of this paper is to show the influence of chronographical works on ancient literary criticism and philology in Rome between the end of the first century BC and the beginnings of the first century AD. In the first part, the development of chronographic tradition in Rome at the end of the Republic is briefly sketched (par. 1). The second part of the paper deals with the relevance of this kind of works for the literary analyses exposed in Cicero’s (...) Brutus (par. 2), in Velleius Paterculus’ history (par. 3) and in Dionysius of Halicarnassus’ treatise On Dinarchus (par. 4). (shrink)

Le processus qui a conduit aux événements d’octobre 2019 au Chili a généralement été interprété comme l’effet explosif d’une « accumulation » de troubles, qui s’est développée au cours des trois décennies qui ont suivi la fin de la dictature de Pinochet. Avec le résultat négatif du plébiscite du 4 septembre 2022 la métaphore de l’« accumulation » est tombée. Qu’est-ce désormais que cette révolte sans révolution? La révolte est-elle un moment interne au néolibéralisme?

The editor's introduction discusses Clarence I. Lewis's conceptual pragmatism when compared with post-empiricist epistemology and argues that several Cartesian assumptions play a major role in the work, not unlike those of Logical Positivism. The suggestion is made that the Cartesian legacy still hidden in Logical Positivism turns out to be a rather heavy ballast for Lewis’s project of restructuring epistemology in a pragmatist key. More in detail, the sore point is the nature of inter-subjectivity. For Lewis, no less than for (...) the Logical Positivists at the time of the Protocols Controversy and Husserl in the Cartesian Meditations, this is a problem without a solution. The reason is that all these philosophers are apparently unable to realize that the existence of a plurality of knowing subjects cannot be treated at once both as a speculative problem and a methodological one. Lewis, thanks to his pragmatist approach both comes closer to the right answer and offers an even more naïve unsatisfactory solution to the pseudo-problem under discussion. The fact that he has clear in mind that inter-subjectivity means not only a plurality of linguistic utterances but also a co-existence of different kinds of practical behaviour. Eventually, the very idea of mind, the key-idea in the book, suffers from the above mentioned tension. In fact, if inter-subjective communication and action is considered at a methodological level, the very idea of mind would not need an analysis, and no kind of ‘reflexive’ analysis. Methodology might be limited to a ‘naïve’ level where the existence of the world and a plurality of subjects be taken as a bedrock of uncritically accepted evidence. Philosophical reflection on ultimate evidence, instead, would take a different approach, maybe the one Wittgenstein was putting into practice in the same years when Mind and the world order was written, namely it would be bound to question the very meaning of the idea of ‘mind’ as an undue fiction – the same carried out by Descartes – when he assumed the Cogito to be at once a body of self-evident truths and a thing or substance, the familiar Platonic idea of psyche or soul.

Sergio Moravia's The Enigma of the Mind (originally published in Italian as L'enigma della mente) offers a broad, lucid, critical and historical survey of one of the fundamental debates in the philosophy of mind: the relationship of mind and body. The book has two central aims--to sketch the major recent contributions to the mind-body problem from philosophers of mind, and, once this framework is established, to articulate a particular interpretation of the mental and the mind-body problem.

Le site d'éditeur indique : "Se il reale fosse semplice, non avremmo molto da pensare, saremmo di fronte alle parti ultime, agli elementi fondanti dell'essere; la complessità è dunque la vera causa, e il vero oggetto, del pensiero umano, sfida indefinitamente aperta per ricondurre il caos amorfo ad una máthesis universale. Non si può dunque fare la storia della complessità, si dovrebbe ripensare tutto il pensiero. Il non potere dire tutto non ci esime, tuttavia, dal dire qualcosa. Il tema della (...) complessità è attualmente oggetto di molte riflessioni da parte di studiosi di discipline tanto scientifiche quanto umanistiche. Il termine è utilizzato con sempre maggiore frequenza e di-mestichezza in diversi contesti di discussione e in numerose pubblicazioni, scientifiche e non, che negli ultimi decenni hanno trattato il tema, rischiando anche, talvolta, di contribuire a generare incertezza sulla corretta accezione. Sebbene l'uso 'popolare' del termine, riferito a situazioni di vita quotidiana, sia normalmente associato a problematiche di difficile se non di impossibile soluzione, l'accezione tecnica, propria degli studiosi di questa o quella disciplina, realizza invece un gradiente ampio di significati, non sempre sovrapponibili, e difficilmente riconducibili ad un comune denominatore. L'opera, nell'auspicio di offrire uno stimolo al lettore, sollecitandolo soprattutto a lasciarsi coinvolgere nell'appassionante dibattito che mette a confronto matrici culturali diverse, intende, innanzitutto, riconoscere la rilevanza del contributo di ogni singola prospettiva disciplinare, la cui capacità di andare in profondità e di cogliere aspetti particolari rimane insostituibile; d'altra parte, intende intercettare elementi di comunanza e di convergenza che consentono il recupero di una unitarietà dei fenomeni che sempre più spesso si vede frammentata nella separazione disciplinare, ma che rimane una realtà e forse soprattutto un valore.".

Les hormones sexuelles sont des objets hybrides et complexes à la frontière du sexe et du genre. Dès lors qu’elles sont synthétisées sous forme pharmaceutique, elles peuvent attribuer des caractéristiques sexuelles au corps de manière partiellement exogène à celui-ci. Il s’en suit que l’utilisation clinique qui en est faite est socialement réglementée. À travers une analyse de divers contextes d’utilisation des hormones observés à Bahia, au Brésil, cet article montre que le dualisme sexuel est le produit de pratiques de régulation (...) biomédicales qui visent à encadrer la circulation des hormones. Le sens du terme local « hormônio » n’est pas pleinement recoupé par celui d’hormone, qu’il excède. L’emploi commun qui est fait au Brésil du singulier procure au terme « hormônio » une qualité fluide et homogène. Dans ce contexte, les hormones sont comprises comme une sorte de substance qui peut circuler entre les corps. Cette conceptualisation des hormones comme une substance a des implications pour le statut ontologique des corps et révèle la relative plasticité de la relation sexe/genre. (shrink)

Background: Job satisfaction is largely associated with organizational aspects, including improved working environments, worker’s well-being and more effective performance. There are many definitions regarding job satisfaction in the existing scholarly literature: it can be expressed as a positive emotional state, a positive impact of job-related experiences on individuals, and employees’ perceptions regarding their jobs. Aims: No reliable scales in Arabic language to assess job satisfaction in the sports and physical education field exist.This study aimed to trans-culturally adapt and validate the (...) Pepe’s “Teacher Job Satisfaction Scale” 9 items (TJSS-9), creating the “Teacher of Physical Education Job Satisfaction Inventory” (TPEJSI) in Arabic language. This scale was administered to a Tunisian population of sports and physical education teachers and analyzed according to the Pepe’s theoretical model.. More in detail, this investigation systematically tested its factor structure, in terms of internal consistency/reliability, predictive validity, sensitivity and convergent validity. Methods: A total of 417 Tunisian teachers of sports and physical education participated voluntarily in this study. The sample comprised of 258 males and of 159 females. More in detail, 189 were teachers teaching in primary schools of physical education, 105 teaching in secondary schools, and 123 were university teachers. Both exploratory (EFA) and confirmatory (CFA) factor analyses were performed on random-split halves of the sample. Results: The three-dimensional alpha coefficients of the TPEJSI were all greater than 0.80: for satisfaction with colleagues, alpha was 0.865; for satisfaction with parents, alpha was 0.856 and for satisfaction with students alpha was 0.860. The CFA fit indices were satisfactory. Conclusions: Given the good EFA factor loadings, the CFA fit indices, the correlation matrix, the sensitivity analysis, the convergent validity and the excellent internal consistency, it can be concluded that the TPEJSI is a good psychometric tool that can be used to quantitatively assess the job satisfaction level among teachers of sports and physical education in the Arabic-speaking world.
